TRANSFER CAR FOR ANNEALING FURNACES.

applicativa :ned March 1a, 1925.' ser'ii No. 15,304.

This invention relates to annealing furnaces and more particularly to a furnace including a heating chamber and a slow cooling chamber in which a transfer car is used" forconveying the heated material from the heating chamber to the slow cooling chamber, and the objects of the invention are to provide a rack and pinionmechanism for delivering the material on to the transfer car and removing it therefrom, the material being preferably located upon a car arranged to be moved into each chamber of the furnace from the transfer car, a rack being provided upon the material handling f car and a pinion upon the transfer car, a

portion of the rack being hinged and arranged to be swung back upon its lhinge to permit the transfer car to pass freely in front of the chambers of the furnace after they are charged.

An embodiment of the invention is illustrated in the accompanying drawings, in whichy l Figure 1 is a plan sectional View of a furnace embodyingl the invention, taken substantially on the line 1--1, Fig. 2;y i

Fig. 2, a longitudinal, vertical, sectional view through the furnace;

Fig. 3, an enlarged detail sectionall View` showing the rack and pinion means for movin the material carrying car to and Y from t e transfer car;

Fig. 4, a` detail sectional lview of the hinged rack; and v Fig. 5, a plan view of the same. ,Similar numerals- Of reference indicate corresponding parts throughout the drawings.

The furnace comprises a heated chamber 1 arranged to be heated by any well known means, such as the electric resistors 2 and an unheated chamber 3, preferably located adjacent and parallel to the heated chamber. A door, sich as indicated at 4, is prefprovided for closing each of the cham ers.

In operation, material to be annealed lis placedin the heated chamber 1 and brought to thedesired temperature, after which it is removed and placed in the slow cooling chamber 3 and permittedto slowly cool tO produce the desired annealing/effect.

The material is preferably carried upon a car 5 rovided with a hearth portion 6 of fire brick or the like, and having the wheels 7.arranged to travel upon the tracks'8 in the bottom of the chambers 1 and 3.

' For the purpose of moving the car 5, with `ranged to register with the tracks 8 in the chambers 1 and 3 to receive the material carrying car 5. A mot/or 15 is carried upon the transfer car and through the gearing 16, drives a pinion 17 arranged to mesh with the rack bar 18 upon the under side yof the material carrying car.

The outer end portion of the 'rack bar comprises a section 19 hingedly connected lto t e end of tliestationary bar as at 20 and arranged to beheld in the extended or operative position, shown in Fig. 2, by the pivoted latch bar 21.

This hinged extension is necessary in order to move the material carrying car 5. entirely into either of the chambers 1 or 3 and itl is also necessary that this `section of the rack bar be hinged in order that it` may be thrown back against the car, as shown in Fig. 3, to permit the transfer car tobe moved upon its tracks 13 without interfering with the rack bar. The latch member 21 may also be thrown back against the end of the` cai', as shown in Fig. 3, thus permitting the transfer car to be moved past the end of the furnace chambers.

When it is ydesired to `withdraw the car 5 from either of the furnace chambers, the transfer car is placed in position in yfront of said chamber and the hinged section 19 ofthe rack bar is lowered into engagement with the pinion 17 and locked in this position by means of the latch bar 21, permitting 'the car 5 to be withdrawn from the furnace lmoved upon said' tracks, a rack upon the material carrying car,1a driven pinion up-V on the transfer cai' for engagement with said rack, anda hinged section upon said llO rack arranged to extend beyond the end lof the material carrying car.
